The oldest monastery in all of Seville, it was founded in 1248 by King Ferdinand III. Its importance to the history of Spain is evident in the fact that it serves as the final resting place for several members of the Spanish royal families. Its church is a fine example of Mudejar architecture, with detailed wood carvings and intricate tile work characteristic of the style. While the monastery is open to the public, it remains an active cloistered convent. Be sure to buy some freshly baked goodies from the nuns, who sell their local delicacies visitors with a sweet tooth.
